Hi,
For your questions.You can use a filter and enter E>2.6KV/mm.
have fun comsol!

Thanks That worked.

But that was just the tip of the iceberg.
i am ploting an electric field of a simple conductor wire surrounded by air.
I want to plot the electric field that is bigger than 2.6 [Kv/mm], i think it worked.. but I also wanto to plot a function: a_ff=p*(k*(((es.normE/p)-a)^2)-A), I already defined p,k,a,A as constant parameters, And i needed this funtion to be ploted just values higher than 0. how can I do this?

I need this results because i need this stationary data to use the charge particle tracing module. but that is the second problem. I am trying to calculate the trayectory of moving particles in the electric field. i am using massless formulation, define the inlet and wall, and the particle velocity. but my doubt is when I define the dependant variables. how can i calculate an integral of the function that I mentioned before and to be ploted just with the data that fullfill the conditions of E>2.6 kV and a_ff>0

so sorry,I want to simple.
for you questions.Maybe you can define a Integrotion, and Define variables enter intop1(your function*( E>2.6[kv])*(a_ff>0))
